If you want other people to like you, then you should care. If you don't, then it doesn't matter.

I don't know about changing oneself, in order to gain the acceptance of others. It's a philosophy I personally don't subscribe to. Mine is basically, accept me the way I am or f**k *ff. 8^)

I am also amused that women (and I'm really generalizing here so cut me so slack) are intially attracted and marry men for the way they are. Then they spend the rest of the marriage trying to change them and mold them into something more ideal. Takes years of training, and an infinate amount of patience on the part of the woman. 8-)
